Abstract: It is difficult for many building gray spaces to define from current norms. In particular, the stability requirements of building components under the conditions of aging, wind disaster, fire and many other disasters can not achieve a balance between the landscape effect and security prevention. Based on the actual case of a city’s gray space landscape construction and combined with the Public Security Triangular Theory, from the point of fire safety,this paper explores the safety analysis method for standardizing such scenarios from the analysis process and contents.

Key words:  public safety, triangular theory, fire simulation;risk prevention
